Background:Postoperative pain is considered as a reason of patient’s delay in discharge and disability aggravation. Therefore, multimodal approaches have been suggested in order to mitigate pain and decrease postoperative side effects.Objectives:The aim of this study was to evaluate analgesic effect of a single dose injection of dexamethasone on reducing postoperative pain in laparoscopic cholecystectomy.Patients and Methods:In this double-blind, prospective study, 122 patients aged 18-60 years old, whom were selected for laparoscopic cholecystectomy, were classified into two case and control groups, and 61 patients were included in each group. The case (D) group underwent general anesthesia and a single- dose intravenous injection of dexamethasone. The Control (C) group received general anesthesia and intravenous injection of normal saline. Total dose of consumed meperidine and pain intensity during first 24 hours were evaluated in both groups.Results:No significant difference existed between two groups regarding age, sex, weight and operation time. Pain intensity in group D was significantly less than group C (P < 0.01) after two, six and 12 hoursof surgery. No significant difference existed in pain intensity between two groups at the beginning of and 24 hours after the surgery (P > 0.05). Meperidine consumption in group D was significantly less than group C (P < 0.05).Conclusions:Findings of present study showed that single dose of intravenous dexamethasone, led to less pain intensity and amounts of meperidine consumption, in comparison with placebo.

Purpose This study aimed to determine the effect of exogenous melatonin on the number of sedative drugs and the duration of mechanical ventilation in traumatic intracranial hemorrhage patients in ICU. Methods This double-blind randomized clinical trial study was conducted in the ICU wards of Golestan Hospital, Ahvaz, Iran, from September 2017 to March 2018. In this study, 52 patients with intracerebral hemorrhage were selected by convenient sampling (26 patients in each group) and were randomly assigned to two groups of melatonin and control. Sedation and pain management package was applied to both groups. Outcomes: Amount of the sedative and opioid drug; mechanical ventilation time; ICU staying time; Glasgow Coma Score; hemodynamic parameters. Results There was no significant difference between them in terms of demographic characteristics. Cumulative doses of morphine and mechanical ventilation time were significant in two groups. ( P < 0.05) The mean length of ICU staying was not significant. Glasgow Coma Score on the 6th day was significant in two groups ( P < 0.05). Diastolic blood pressure was significant between groups ( P < 0.001). Conclusion This study presented that morphine consumption and mechanical ventilation time were significantly lower in the melatonin group than in the control. Also, rise in GCS in the melatonin group was faster in the melatonin group than in the control. The use of melatonin can be recommended for patients with ICH in the ICU for better outcomes.

BackgroundOpen prostatectomy is still accompanied by some postoperative bleeding. Prescribing fibrinogen to promote clot formation in patients with bleeding is of critical importance. This research studied the effects of local injection of fibrinogen on level of postoperative bleeding in open prostatectomy.MethodsOverall, 44 patients were randomly entered in a study on open prostatectomy. Patients in the intervention group received local injections of 500 mg fibrinogen (20 mL) dissolved in distilled water, and the control group patients only received 20 mL of normal saline, where the injections were given by the surgeon at the prostatectomy operation site. All patients were tested for hemoglobin, hematocrit, PT, PTT, INR, and fibrinogen level. Also, the amount of blood loss and requirement for blood products were recorded.ResultsThe study groups showed no difference regarding baseline variables. One patient in the fibrinogen group (1.66%) and four patients in the control group (6.66%) received blood products (P < 0.05), and the blood drainage tube at 24 hours after operation was 36.50) 18.70 (mL in the fibrinogen group and 151.36) 120.58 (mL in the control group (P = 0.005). There were no differences in hemoglobin, hematocrit, PT, PTT, INR, and serum fibrinogen level between the groups at any time.ConclusionsThe current study demonstrated that using fibrinogen in patients with high bleeding risk may effectively reduce the amount of bleeding and its subsequent blood transfusion requirement, after open prostatectomy surgery.

Background: Comparison of midazolam and propofol has been done hoping to reduce the incidence rates of emergence agitation (EA) after anesthesia. Both drugs however, are still under inspection as for their effect on EA after using Isoflurane for maintenance of anesthesia. Objectives: This study was designed for measuring the effect of either propofol or midazolam near the end of tonsillectomy operation on incidence of EA during the recovery phase. Methods: In this randomized, double-blind study, 90 children, aged 5 to 15, undergoing anesthesia with Isoflurane were randomly assigned to three groups receiving either propofol (group P), midazolam (group M) or saline (group S) near the end of anesthesia. Severity and incidence of EA were then calculated using the pediatric anesthesia emergence delirium (PAED) scale. Results: The mean PAED score in group P was (2.87 ± 2.69) and (1.90 ± 2.55) in group M. Both were significantly lower than group S (7.60 ± 3.78) (P < 0.05). However, there was no statistical difference in the duration of post-anesthesia care unit (PACU) stay between groups P (42.50 ± 12.58) and M (48.33 ± 24.26), groups P and S (52.00 ± 10.64) and between groups M and S (P > 0.05). No significant difference was found between all groups for apnea and laryngospasm (P > 0.05). Conclusions: Administration of either midazolam or propofol near the end of operation may result in reduction of EA in children undergoing tonsillectomy after Isoflurane anesthesia.
